🦋 DESCRIPTION 🦋

okay so the vibe check: this function is called after each erase operation, and it removes PEBs from the tail of the protection queue. those PEBs have been protected for long enough, and they should be moved to the used tree. literally the whole glow-up: tail of the protection queue → used tree. no cap. 🔥
